tMRovED MACHINE ,FOR ROLLING METALS,

The Schedule referred to in `these Letters Patent and making part Vof the saine.

l'o allxwhomitmay concern: y

Beit known that I, ANDREW'KLOMAN, of Pittsburg, in the county of Alleghenyand in the State of Pennsylvaniahhave inventeda new and useful Improvemcnt in' Machine for Rolling Iron; and I do hereby declare the lfollowing to be atu'll, clear, and

exact descriptionthereof, reference being had to the accompanying drawing, in two sheets, making a part of this specification, in which- Figure 1 is a front elevation of my improved machine;

Figure 2 is a rear elevation thereof; and

Figure 3 shows a horizontal section as `formed by a plane passing through the machine just beneath the upper horizontal roll.

Like letters of reference indica-te like parts in each.

My invention consists in the construction of an improved machine for rolling fiat plate iron of any desired width and thickness.

To enable others skilled in the art to make'and usc my invention, I will proceed to describe its construction and mode of operation.

The horizontal rolls A A', of the usual or any desired-construction, are mounted in the housings in the usual way. l

The upper rollA is so set in its bearings that it maybe adjusted up or down by means of a screw, m, and by a counterpoise, so as to 'givea greater or less opening between it and the lower roll A. 1n this way the rolls areadjusted, 'so as to roll plates of the desired thickness, or to reduce them in thickness ateach successive pass.l

In front of the rolls, extending from one housing to the other, is a guide-rest, b, consisting of two parallel bars, properly set with reference to the plane Vof the Fpart of the rolls. 0n this is set a pair -of guides', n, at c, on the lower face of each guide c., passing-down between the bars of the guide-rest b, and cn- -gagug their lower'face.

Through the Shanks al Va hand-wheel, 'd'. t

It is then obvious that by turning the hand-wheel d' the guides a maybe readily and accurately set at` any required distance'apart, and that snch distance -can be almost instantly changed.

For convenience, the inner faces of the 'guides a may be shouldered as at m2 the horizontal face vofthe- Vshoulder being even with the upper face of the lower roll A.

0n the rear side of the rolls A A', and extending of the T-shaped guide a, aV right and left-hand screw d, is operated, by means of i .To this end a pair of screws, f f', operate through each housing, with their forward'endsj attached by means of keys, c, and grooves, c', to the adjusting blocks D'. Then, by turning the screws f, by means of .their headsf, or by means of gearing connected therewith, the vertical rolls may be set to or from each other, as may be desired.

By connecting the screws f with a common source of power, they may, likethe guides c, be each adj usted simultaneously and uniformly, and with equal accuracy.

These upright rolls form the edge of the bar or plate to be made.

The power, to operate the the vertical rolls D D is communicated through any suitable arrangement of gear-wheels, 'n n, to the shaft y, on which, by a key, i, and groove, fi', or in other equivalent manner, the unter-wheels It are set, so that they are adjustable forward and back on the shaft q.

This adj ustmcnt is effected by means of a yoke, o, attached to the adjusting blocks D', the end of' each yoke o entering a groove, o'. in the h ub of each gearwheel hv. Then, as the adjusting blocks are moved forward and back, they carry the ruiter-wheels h with them, so that all -points of adjustment the latter will mesh into the corresponding unter-wheels l1', ou the ends or necks of the vertical rolls D D, and so conimunioate inotiont-o them.

The adjust-ing blocks D and necks of the vertical rolls D may be connected by straps or' other suitable bearings. l

The billet, bloom, or pile to be rolled, being first heated, is fed in between the guides a, the guides being set to the width of the billet, bloom, or bar, as it is passed in, the horizontal rolls being adjusted so that they will reduce it the desired amount at the first pass, and the vertical rolls heilig adjusted so that they will engage the edges of the bar or plate as it comes through. \Vith the devices heretofore in use, it has taken so long a time to readjust the rolling and feeding devices, that before the rolling out of a si-ngle plate could beeected, it. had lost so much of its hea-t that the rolling had to be suspended, with'a consequent loss of time and waste of' fuel, while the ,plate was taken to the furnace and reheated.

Nor do I know of any machine heretofore in use in which `the guides would receive an iustant a11eous, simultaneous, and accurate and variable length of throw to or from each other; and this, element constitutes'one of the important features of my invention.

\Vhiie the bar or plate is being passed from the rear side of the rolls back to the front, for another pass between the rolls, the operator in charge, l y

turning the hand-wheel rl', can almost instantaneously,

`and with most perfect accuracy,

set the guides a to the width of the bar or plate, so as to feed it in suoli position that both its edges will be again engaged by the `"crtical rolls, which are likewise adjusted in the manner already described. I am thus enabled to save one or two or more heats in the rolling out of a bar or plate, and, also, secure greater uniformity in the work produced.

1f found desirable, the guides ay may hc'sct in each case a distance apart, alittle in excess of the width of the 'bar or plate, and then tightened up a little as soon as the bar or plate is introduced between them.

This is especially the case with the tirst pass of' a pile or fagot, since, in beating and handling, it is liable to become twisted or get out of shape.. ln such case, the guides may be opened to receive the pile, and then closed sutliciently to feed it .through at the proper joint for it to be rolled on both edges by the upright rolls.

Also, likewise the trame-work C ou the rear tbe front rest D maybe graduated as at s', and ofthe machine,

as at s', for greater convenience and accuracy in setting the guides a and vertical rolls D.

ln connection with the guides a, I do notlirnitinyself` in my invention to a right and left-hand screw, d, but include in my invention other mechanical devices of like function, such as a cam, eccentric, Sac., which, being connected with the guides a, will give to both a tln'ow'simultaneous as to time, uniform in extent, and variable at pleasure as to length. A

.Vhat I claim as my invention, and desire to secure by Letters Patent, is#

The parallel-faced guides u, simultaneously adjustable to or from each other, as described, in combination with the horizontal rolls and the adjustable vertina-l rolls, substantially as set forth.

In testimony whereof, 1, the said ANDREW KLO- MAN, have hereunto set niy hand.

ANDREW KLOMAN.
